Irritability in preschool children with attention‐deficit/hyperactivity disorder: Analysis of family environmental factors

open access: yesJCPP Advances, EarlyView.
Abstract Background Irritability affects one‐third of children and adolescents with attention‐deficit/hyperactivity disorder (ADHD) and is associated with negative outcomes. The family environment plays a prominent role in the child's development, and therefore on the risk for irritability, especially during the preschool period.

Iterative Interference Cancellation for OFDM Signals With Blanking Nonlinearity in Impulsive Noise Channels

open access: yes, 2013
A simple iterative interference cancellation scheme for orthogonal frequency division multiplexing (OFDM) signals with blanking nonlinearity in impulsive noise channels is presented. Blanking nonlinearity has been widely used in practical OFDM systems to

Target Detection in Continuous-Wave Noise Radar in the Presence of Impulsive Noise

open access: yes, 2011
In the paper a problem of target detection in continuous-wave noise radar in the presence of impulsive external noise is addressed. Noise radar uses random or pseudo-random waveform as a sounding signal. Classical correlation receiver used in noise radar

Voice and Speech in Atypical Parkinsonian Disorders

open access: yesMovement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.
